85% to 95% of the leases signed in San Diego are found through Craigslist. Most all owners, management companies and agents advertise their rentals on Craigslist.
Here is the link to the San Diego rental site. Put the zip code in the search box and then select the rest of your settings. You can find all of the zip codes for mira mesa and surrounding areas using Google.
Know that the rental market here is fast paced, so check the listings a couple of times a day and contact the renting party as soon as possible.
Best of luck,
